This nnid 'guard *.15 is transversely curved so as to readily shedinud and water, and is bent longitudinally to conform to the general vshape of the lever arni 7a. I The longitudinal edges yof the niud` guard slightly overhang the sides ofthe lever so that there will be no danger of inud and water accumulating within the channel shaped lever and causing rusting and corrosion of the parts,r as well as interfering with the freedom of imovement thereof. The outer end of the mud v guard may be provided with laterally prothereby providing a limited movement ofy play and preventing undue strain upon the parts when there is an unusually heavy rebound of the vehicle body. This construction avoids the necessity of using a shackle,`

and the arrangement of the levers is such that the resiliency of the main spring Ll will be supplemented by 'i that of the 'tension springs 12,- thereby causing all sudden shocks and to be effectively absorbed and imparting .easy riding qualities to the vehicle.

Having thus described the invention, what I claiin as new and desire to secure byIi'et# ters Patent, is

l. A' shock absorber for vehicles having transversely disposed springs, including a perch rigid with the axle and projecting upwardly therefrom', ay lever formed` .-\vith l two arins which are arranged at an angle to each other, the outer arm being'formed with side flanges and having a channel shaped cross section, while the innerarm is bifurcated and the halves thereof form continual tions of the ianges of the outer arm, a pivot bolt connecting the endy of the spring to the lever at the interse'ctionof itsy angularly disposed arms, the outer arm being'ipivotally` connected to the perch, while the inner paring extends under the vehicle spring, and tension springs connecting the two halves of the bifurcated inner arm to the vehicle frame.

2. A shock absorber for vehicles :having transversely disposed springs, including a vperch rigid with the axle and projecting upwardly therefrom, a lever having vthe same direction as the spring and piyotally' con,` nected at an intermediate point in its lengthto the extremity of the spring, lthe outerend of the lever extending beyond the end of the spring and being pivotally connected to the perch, a tension spring connecting the inner end of the lever to the vehicle frame, and a mud guard applied to the lever and extendking over the pivotal connections thereof to exclude accumulations of inud and dirt.
